target spec: remove /etc/rustc as default path 

The RFC specifies that if RUST_TARGET_PATH is unset then the default is
/etc/rustc but this won't work on all systems (e.g. Windows) and the
Rust compiler never actually implemented this behavior so remove it from
the RFC. closes rust-lang/rust#31117

@ -65,8 +65,7 @@ deciding how to build for a given target. The process would look like:
1. Look up the target triple in an internal map, and load that configuration
if it exists. If that fails, check if the target name exists as a file, and
try loading that. If the file does not exist, look up `<target>.json` in
the `RUST_TARGET_PATH`, which is a colon-separated list of directories
defaulting to `/etc/rustc`.
the `RUST_TARGET_PATH`, which is a colon-separated list of directories.
2. If `-C linker` is specified, use that instead of the target-specified
linker.
3. If `-C link-args` is given, add those to the ones specified by the target.
